I inherited a 1987 Jameco JE1015 from my dad and I'm in the process of restoring it, but it appears that its microcontroller is completely missing... yeah. My dad was probably experimenting with it and just never put it back together correctly.
I know this is a long shot, but does anyone have a this or a similar board that's willing to take it apart and photograph the IC for me? The controller is a 40 pin DIP and that's really all I know about it, I'm hoping that it's a commonly used keyboard controller that I can find a datasheet for (even that's probably a long shot). My plan is to trace out the PCB and replace the controller with a Teensy, and having the datasheet would make it much easier.
Thanks in advance!
